Analcime on calcite

This perfectly formed single analcime crystal from the Jender valley beneath conca Zemmer is a rare find. Datolite crystals were also found here before 1900, but the site is depleted due to the rush of collectors. The area on the Alpe di Siusi between Jender river and Ciapit river in the west has revealed well-known mineral discovery sites in volcanic rock from the Triassic era (Ladinum)
